Help, I am planning my first attempt in the next few days, I have been exercising 6 days per week. I do a cardio dvd three times per week. In advance of my sway I have been reading up on stuff to see if I could tighten my sway and I re- read the stuff on cardio and am now nervous, the dvd involves using some weights during part of the reps to add weight to increase the calorie burn but now am worried that is building muscle? Given how little I eat some days I cannot see how it could but interested in thoughts? Some days am over my levels and I still exercise. Should I push my sway back? Many thanks
